Silica is one of the potential minerals to be developed and applied in various industrial fields. High purity of silica can be obtained by utilizing natural materials such as beach sand. In this research the solid-liquid extraction (leaching) method was used in three main steps.

From Sand To Flat Glass

From Sand To Flat Glass

Sand is critical to flat glass manufacturing since it is the principal source of silicon dioxide (SiO 2) which is essential for producing glass [2]. A high proportion of silica in the sand composition (above 95%) is therefore required together with a high level of chemical purity. This quality of raw materials is all the more important for flat ...

How Is Silicon Obtained? | Ehow

How Is Silicon Obtained? | Ehow

The Production of Pure Silicon. Pure silicon is produced by heating silicon dioxide along with carbon in an arc furnace at around 1900 degrees Celsius. The heat causes the oxygen in the silicon dioxide to split from the silicon and bond with the carbon. Hence, the outputs of this process are pure silicon, carbon monoxide and carbon dioxide.
